You would rather get build number.

Build numbers simplify everything, Windows 7 build is 7600, SP1 version is 7601.

#define WinBuild "7600"

procedure GetSysInfo(var SysInfo: TSysInfo);
external 'GetSysInfo@files:Isab.dll stdcall delayload';

var SystemInfo: TSysInfo;

GetSysInfo(SystemInfo);

function CompreWindows:Boolean;
begin
Result:=SystemInfo.OSBuildNumbers>={#WinBuild};
end;
